Yes, I appreciate what you say re Touchpads. I hate them too!
So, solution - get a travel or bluetooth mouse :) I use both types, depending on what device I'm using. I've tended to use MS wireless mouse's and have a MS and Dell Bluetooth mouse. All are excellent although not the cheapest available.
Check out websites to see what's available - you'll find there's a huge variety.
You'll also want to check what keyboard shortcut to use to disable your Touchpad, otherwise just brushing your arm/sleeve over it will send your cursor all over the place.
Please post back with outcome ;)
